I think everyone knows that DRM does not work except to make money for the company's that produce DRM.
There are two types of pirate.
One downloads a game and plays it to its conclusion having no intention of purchase.
The other downloads a game, plays it for a hour or so, if they like it they buy it, if they don't like it then they delete it from their computer.
One is a thief and the other is just being careful with their money.
